TRANSFORMER BOX. AND HANGER.

SPECIFICATION forming part of Letters Patent No. 606,208, dated June 28,1898.

Applicationfiled November 22,1897. Serial No. 659,426. (Nomodel-l To allwhom, zit may concern:

Be it known that I, LUDWIG GUTMANN, a citizen of the United States, anda resident of the city of Peoria, county of Peoria, and State ofIllinois, have'invented new and useful Improvements in Transformer Boxesand Hangers, (Case No. 88,) of which the following is a specification.

The object of this new device is to facilirate the hanging oftransformers and to reduce the amount of time required for this purpose.It has been the general practice to pro-' vide lugs on thetransformer-box to be able to suspend the same. hile this mode issufficient for attaching it to a wall, other means are required tosupport it on a pole, on which most transformers are mounted. For thispurpose a cross-arm and iron hangers are required. The lugs offeradditional inconvenience, as the locating of the holes in a" wall orcross-arm requires the raising of the transformer to its place formarking the holes to coincide with those in the lugs.

Another purpose of the invention is to provide a mode of suspensionwhich may be adopted for all existingeonditions.

To more fully explain the nature of myinvention, the accompanyingdrawings may be referred to in connection with-the description.

Figure 1 shows a front elevation of the preferred transformer-hanger.Fig. 2 shows a side elevation of this hanger. Fig. 3 shows the same inconnection with a transformerbox. Fig.4: is a section through thetransformer box and hanger at lines a l) of Fig. 3. Fig. 5 is a modifiedhanger, and Fig. 6 is a section of this hanger.

Referring in particular to Figs. 1 and 2, the hanger consists of a mainplate A, of metalfor instance, cast-iron. It is provided with a numberof holes B for admitting bolts or screws for attaching it to a pole,beam, or wall. The size of the plate is so chosen and the holes locatedin such a manner that it may be readily attached to any wall, crossarm,or to any pole. In the latter case it is preferable to remove the curvedsurface of the pole behind the plate, so that it can be screwed home onthe pole and rest firmly against it. The form chosen is triangular,

and the upper two sidesare provided with a raised portion or rim 0,which has the form of an inverted V.

Figs. 3 and 4 show the application of this hanger. On the back of thetransformer-box D is cast a raised rib E, forming an inverted V. Thisrib is provided with the groove F, (see Fig. 4,) into which the rim 0may readily slide.

Fig. 5 shows a hanger-plate of rectangular shape. The same may be madeto have the flanges G slightly tapering, so as to wedge into asuitably-formed set of grooves on the back of the transformer. (Shown indotted lines.) Fig. 6 shows this plate and the back of a transformer-boxin section. The flanges E on the transformer-box are not parallel, butcome nearer to one another at the upper end. The plate just describedenters with the smaller end first into the groove F, wedging itself intoposition asit advances in the groove. This last condition is notabsolutely necessary. The sides 0 C may be parallel, as also the groovesF. In this case some means must be provided to prevent the plate A fromslipping through at the upper end. These means consist in closing thegrooves F at the upper end, as indicated by the dotted lines G G. TheWeight of the transformer rests in this case on these twolugs thusformed, while in Figs. 1 and 4 the weightis carried by the entire lengthof the flanges E E.

This construction m akes the mode of hanging very simple. The linemantakes the hanger-plate of small weight upon the pole or place to befastened and drives lag-screws into the holes B, thus securely fasteningthe hanger-plate A. Then the transformer is raised slightly above theplate and then lowered, so that the rim 0 slides into grooves F. Theweight of the transformer downward will wedge it on the hanger, fromwhich it can only be removed by again hoisting it up.

It is evident that my invention may be modified in a variety of wayswithout departing from the nature of the invention. For instance, thelower holes B of Fig. 1 may be substituted by slots extending to the rimof the plate. Further, the shape of the plate or its rim may be given adifferent form. Therefore I do not wish to limit myself to the exactdevice shown in the drawings.

Having now fully described the nature of my invention, that which Idesire to claim as.

my invention is- 1. In a transformer-hanger the combination of a mainbody tapering toward the upper end, a tapering rim forming part of saidhanger, located in a parallel plane to the main body, and holes orrecesses in said main body for retaining screws, bolts, or other devicesfor fastening, as and for the purpose described.

2. In a transformer-box the combination with a receptacle for inclosinga transformer, 01": a groove or recess provided on one of the sides ofsaid receptacle, a removable plate adapted to be retained in saidrecess, and means, such as holes in said plate, as and for the purposedescribed.

In a transformer-box the combination of a receptacle, a projecting rib,or ribs, provided with a slot or recess, a removable plate provided witha rim, normally engaged with said recess, and means, provided in saidplate, for its attachment to a suitable support, as and for the purposedescribed.

I. In a transformer-box the combination of one or more projectingchannels extending from a side of a receptacle inclining toward eachother, adapted to retain a supporting plate or bracket, and a removableplate or bracket normally retained in said channel, and means, such asholes in said plate or bracket, for suitably attaching; it, as and forthe purpose described.

5. In a transformer-box the combination of a bracket or plate, means,such as holes, or recesses forattaching said plate to its place, and aprojecting rim, a metallic box provided with an extension containing arecess normally engaging with said projecting rim, but removable fromthe latter in an upward direction.

6. In a hanger-plate the combination of a triangular main body A, aprojecting flange located in a plane parallel to said main body, andmeans such as holes or recesses in said main body, as and for thepurpose described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two Witnesses, this 11th day of November, 1897.

LUDlVIG GUTMANN.
